DIVIDING STRIP STRUCTURE Patented Nov. 13, 1934 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to a dividing strip and construction particularly useful in forming integrally with a terrazzo floor surface, a lower wall surface or baseboard.

8 Terrazzo floors are of course widely used. For sanitary reasons it is desirable to avoid joints or cracks at the juncture of the floor and wall. It is also desirable to have the lower or baseboard portion of the wall surface made of a material 10 which will withstand water and mopp This can be obtained by forming a terrazzo baseboard, several inches in height, integrally with the terrazzo surface layer of the floor. Ordinarily the wall surface above the terrazzo baseboard will be coated with plaster; and it is desirable to provide a suitable construction for the meeting of the plaster and terrazzo, and for permitting the independent laying of the terrazzo ,and plaster.

' An object of the invention is to provide an economical and satisfactory construction for forming a plastered wall surface, with a terrazzo baseboard and floor surface.

Another object of the invention is to provide a simple inexpensive dividing strip which facilitates the independent application of the terrazzo and plaster.

Fig. 1 is an isometric view showing more or less diagrammatically a dividing strip of the p esent invention separating wall plaster and a terrazzo baseboard.

Fig. 2 is a section taken approximately on the line 22 of Fig. 1.

, There is provided a supporting wall structure '1, of any suitable type (e. g. gypsum blocks) having a surface adapted to receive plaster-like materials. There is also provided a suitable supporting floor structure 2 to which the floor layer of terrazzo is applied. Usually, the structure 2 40 shown in the drawing is a heavy coat of cement mortar known as the screed coat.

The dividing strip as shown consists of a plane strip of material 4 (usually metal and frequently brass) of suitable thickness and strength. The

strip is provided with a plain edge 5 to be exposed in the finished wall surface. Attached to the strip are fastening means in the form of separate L-shaped pieces designated as a whole by 6. One leg of each piece 6 is in contact with the side of the strip, and the other leg is in contact with the edge of the strip and projects laterally, forming an ear 7. The separate pieces 6 are attached to the strip in any suitable manner as by welding, soldering, brazing, riveting, etc. An excellent at- 5 tachment is obtained by means of eyelets or tubular rivets 9 because'they can be easily drawn up tightly without kinking the strip. It will be noted that the contact between the leg 7 and the edge of the strip is such as to prevent rocking of the separate piece, and thus a firm and economical attachment of theseparate piece to the strip can be obtained with a single rivet. I Each of the fastening means 6 is provided with a nailing hole 8, and the strip is attached to the wall supporting structure 1 by nails 10 which are inserted through the holes. Plaster 11 is applied to the wall in the usual manner, extending downwardly to the dividing strip. Terrazzo 12 is applied in the usual manner over the floor supporting structure at 12 and up the wall structure to the dividing strip. If desired, the terrazzo applied to the wall may be backed with a screed coat 2*. Since the dividing strip is secured to, and carried by, the wall supporting structure it is immaterial whether the plaster be applied first or the terrazzo be applied first. Thus the inven tion provides flexibility and convenience in carrying out the building construction. However the grinding of the terrazzo surface is a rather messy operation; and with the present invention the surface of the floor 12 and the surface of the baseboard 12* may, if desired, be ground before the plaster 11 is applied. Thus danger of staining the plaster during the grinding of the terrazzo may be eliminated. During the subsequent application of the plaster 11, considerable plaster may get on the terrazzo but it can be readily washed off without any effect upon the terrazzo.

It will be noted that the invention embodies an exceedingly simple and inexpensive cionstruc- 9 tion, which accomplishes its function in a very direct and adequate way. The invention may of course be embodied in forms other than the specific one disclosed, and hence the disclosure is merely illustrative in compliance with the patent statutes and is not to be construed as limiting the scope of the claims.

I claim:

1. A divider for surfacing layers in building construction comprising a strip of material having a plain edge to be exposed in the finished surface; and fastening means permitting the strip to be secured to a supporting face before the surface layer is applied, said fastening means comprising ears extending laterally of the strip at the edge opposite to said plain edge, the ears being shaped and positioned to lie against the supporting face and prevent tilting of the strip.

2. A divider for surfacing layers in building construction comprising a strip of material ha ing a plain edge to be exposed in the finished surface; and fastening means permitting the strip to be secured to a supporting face before the surface layer is applied, said fastening means comprising separate pieces attached to the strip and extending laterally of the strip at the edge 0pposite to said plain edge, said pieces being shaped and positioned to lie against the supporting face and prevent tilting of the strip.

3. A divider for surfacing layers in building construction comprising a strip of material having a plain edge to be exposed in the finished surface; and fastening means comprising separate pieces riveted to the strip, said pieces formin ears'extending laterally of the strip at the edge opposite to said plain edge, the ears being shaped and positioned to lie against a supporting face and prevent tilting of the strip.

4. A divider for surfacing layers in building construction comprising a, strip of material having a plain edge to be exposedin the finished surface; and fastening means comprising separate pieces attached to the strip with'tubular rivets, said pieces forming ears extending laterally of the strip at the edge opposite to said plain edge, the ears being provided with nail holes, and being shaped and positioned to lie against a supporting surface and prevent tilting of the strip.

5. A divider for surfacing layers in building construction comprising a plane metal strip, and fastening means comprising separate L-shaped pieces each of which has one of its legs secured -of said pieces to the strip.

against the side of the strip and the-other of its legs projecting laterally of the strip, the pieces being shaped and positioned to lie against a supporting face and. prevent tilting of the strip.

6. A divider for surfacing layers in building construction comprising a plane metal strip; and fastening means permitting the strip to be secured to a supporting face before the surface layer is applied, said. fastening means being separate angle shaped pieces having a leg in contact with the side of the strip and a leg extending across the edge of the strip and projecting laterally thereof the pieces being shaped and positioned to lie against the supporting face and prevent tilting of the strip.

'1. A divider for surfacing layers in building construction comprising a plane metal strip; a plurality of fastening means permitting the strip to be secured to a supporting face before the surface layer is applied, said fastening means being separate angle shaped pieces having a leg in contact with the side of the strip and a leg extending across the edge of the strip and projecting laterally thereof, some of the fastening means projecting on one side of the strip and others projecting on the other side of the strip and the fastening means being shaped and positioned to lie against the supporting face and prevent tilting of the strip; and a single rivet securing each v HARRY L.
